Water jet cutting machines use ultra-high-pressure water streams to achieve precise material separation without thermal effects<\/figcaption><\/figure>\n

Water jet cutting is a CNC-controlled manufacturing process that uses an extremely high-pressure stream of water – often mixed with abrasive particles – to erode, cut, and shape materials. Unlike thermal cutting processes (laser, plasma) that alter material properties through heat, or mechanical processes (CNC milling) that generate cutting forces, water jet cutting is fundamentally a cold, force-free process. This unique combination of characteristics makes water jet technology indispensable across industries ranging from aerospace to stone fabrication.<\/p>\n

How Water Jet Cutting Works<\/h2>\n

The water jet cutting process begins with a high-pressure pump – typically intensifier or direct-drive type – that pressurizes water to 30,000 to 90,000 PSI (2,000 to 6,200 bar). This ultra-high-pressure water travels through high-pressure tubing to the cutting head, where it passes through a jewel orifice – typically sapphire, ruby, or diamond – with a diameter of 0.003 to 0.020 inches.<\/p>\n
